To all 2 5110127. it may concern:

is it known that I, CLAUD J. GLEFTON, a citizen of the United fiv' 'zates resident of ()watonua, county of Steele, State of Minnesota, have invented certain new and useful Improvements in Acetylene Burners, of which the following is a specification.

The object of my invention is to provide a burner adapted generally for gas and particularly for acetylene gas in the handling of which great difficulty is experienced through the flaring back or poppingof the gas in the mixing chamber when the flow is cut olf. Such flare-back and the consequent explosion usually frightens the person handling the burner and renders the sale of the article difficult and sometimes impossible.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, v

Figure 1 is a plan view of a torch embodying my invention,

Figure 2 is a longitudinal sectional view of the same,

Figure showing the burner in use on a flat iron,

Figure 4- is a perspective View of a gas distributing device provided near the tip of the burner.

In the drawing, 2 represents a shell or casing having a mixing chamber 3 with ports a leading thereto and a threaded orifice 5 to receive a tip 6 that is connected with a hose '4' leading from a source of gas supply. The casing 2 has a passage 8 leading from the mixing chamber and communicating with a chamber 9 provided in the tip 10 of the burner, said tip having a tapered end 11 enclosing an orifice 12 through which the heating flame is projected. The tip is connected with the casing by suitable means such as the threads '13 by means of which the tip can be conveniently removed from the casing or mounted thereon. I V

lVithin the chamber 9 I arrange a sleevelike member 14 having a beveled end 15 to lit the inclined surface of the Walls of the tip and at its other end a cone surface 16 is rovided haviiw ribs or win s 17 thereon which bear on the adjacent end wall ofv the casing 2 and space the sleeve from said wall so that the gas may flow freely between the I 3 is a view, partially in section,.

wings17 and around the sleeve in the chamher 9 between it and the walls ofsthc burner. The walls of the sleeve'I provide with a se' ries of narrow slots 18 extendingpartially around the sleeve and close together so that the gas entering the chamber of the burner is deflected by the walls thereof to these slots and passing through them, may then reach the orifice or exit of theburner. The gas is compelled to make what is substantially two rightangle turns, one to pass from the chamber9 through the slots 18 into. the space enclosed by the sleeve and the other in flowing from the slots to the orifice 12. The air, of course, is mixed with the gasin the burner in the usual way and I have found that there is no flare back or popping of the burning gas when the supply is cutoff; as sometimes happens inv lighting the gas. The flow to the tip of the burner is instantaneous, and it may bevreadily ignited and placed in the fiat iron or any other position where it is desired to use the burner.

In Figure 3 I have shown the burner mounted in a flat iron which comprises a base 19 having a top or cover 20, a standard 21 and a hand grip 22 mounted on the standard, The burner is fitted into a socket 523 at one end of the base and a spring-pressed pin 24 engages a rib 25 on thesurface of the burner for holding it in the socket of the iron. \Vhen this pin is lifted against the tension of the spring; the burner-may be readily withdrawn from the iron. The angle of the burner is such in itssocket that the flame therefrom is projected against the bottom of the iron sothat it will be oughly heated.

I claim as my invention:

1. The combination, with a gas burner having'a tip provided with a chamber and a quickly and thortaperedv end having an orifice leading from j said chamber, of a sleeve fitting within said chamber and having one end seated against the tapered walls of said end oppositesaid orifice and its side walls spaced from; the corresponding walls of the burner to form an annular passage between them, the other end of said sleeve being tapered and he perforate and having means for deflecting the gas outwardly to said annular passage, and the walls of said sleeve having openings therein through which the gas is compelled to flow from said annular passa e to reach 1 the exit of the burner. 1

2. The combination, with a gas burner *having a chambertherein, of a sleeve fitting within said chamber and its side walls spaced fronithe corresponding walls of the burner to form an annular passage between them, said sleeve having a cone-shaped in'iperforate V end provided with means for deflecting the gas outwardly to said annular passage and the walls of said sleeve having open ngs ing imperforate and having webs thereon for deflecting the gas outwardly to said passage,

the walls of said sleeve having narrow slots therein through which the gas'is compelled to flow from said annular passage to reach the exit of said burner.

In witness whereof I have hereunto set my hand this 28th day of February, 1921. CLAUD J. CLEFTON.
